Substitute Part Grouping Explanation

Substitution eligibility for the DS80C320-MNG is determined by strict alignment across the following critical parameters:

• Core processor architecture (8051)
• Core size (8-Bit)
• Operating frequency (25MHz)
• Program memory configuration (ROMless)
• RAM capacity (256 x 8)
• Supply voltage range (4.5V ~ 5.5V)
• I/O count (32)
• Connectivity interfaces (EBI/EMI, SIO, UART/USART)
• Integrated peripherals (Power-Fail Reset, WDT)
• Operating temperature range (-40°C ~ 85°C)
• Physical package (40-DIP)
• Mounting technology (Through Hole)

The DS80C320-MNG+ qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DS80C320-MNG+ is the direct functional equivalent of the DS80C320-MNG. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The DS80C320-MNG+ is classified as Active product status, providing ongoing availability and manufacturer support. The DS80C320-MNG+ achieves ROHS3 compliance, whereas the original DS80C320-MNG is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the DS80C320-MNG+ is the appropriate selection. The DS80C320-MNG+ is supplied in Tube packaging, compared to unspecified packaging for the original part.

Frequently Asked Questions (FAQ)
